No, don't go to the stealership!!!!! Dude. You have super huge tires. Your ABS isn't going to work correctly anyway. Go under the hood, go into the relay panel, and pull the fuse for it for a week or two. It's the big blue 30 (EDIT: 60) amp one, IIRC (EDIT: I have pictures for you below). I'm on 35's, and the difference is amazing. The pedal doesn't fight back.

But, you have to know how to drive. If you pop the facia around the dash off, there are 3 or 4 screws holding your dash panel on. It just pulls out, and you can pull the light. Too easy. That's my unsolicited recommendation for you.
Also, if you're in snow/ice/mud/sand/etc. going down a steep hill and try to slow down without downshifting for compression, often one wheel will slip (usually rear, which causes both rears to lock and then slip), and then your ABS will not allow you to continue to brake, which means you freewheel it down the hill. Not too good for someone at the bottom of the hill, or the front of your very sex rig, if I do say so myself... My $0.02.
edit- here's pictures...

It's the fuse missing between the big, red 50 amp ones.
